SOA Delivery
The delivery of SOA applications and services is just like traditional application delivery - only "more differenter."
#mobile #fasterapp #ccevent Today, at least. Tomorrow, who knows? Some have tried to distinguish between “mobile cloud” and “cloud” by claiming the former is the use of the web browser on a mobile device to access services while the latter uses device-native applications. Like all things cloud, the marketing fluff is purposefully obfuscating and sweeping under the rug the technology required to make things work for consumers, whether those consumers be your kids or IT professionals. Infrastructure is not eliminated when organizations take to the cloud nor do the constraints of web-based protocols and methodologies become...
#v11 Application-centric analytics provide better visibility into performance, capacity and infrastructure utilization Maintaining performance and capacity of web sites and critical applications – especially those of the revenue-generating ilk – can be particularly difficult in complex environments. The mix of infrastructure and integration can pose problems when trying to determine exactly where capacity may be constrained or from where performance troubles are originating. Visibility into the application delivery chain is critical if we are to determine where and at what points in the chain performance is being impaired or constraints on capacity imposed, perhaps...
It’s kind of like thinking globally but acting locally… While I rail against the use of the too vague and cringe-inducing descriptor “workload” with respect to scalability and cloud computing , it is perhaps at least bringing to the fore an important distinction that needs to be made: that of the impact of different compute resource utilization patterns on scalability. What categorizing workloads has done is to separate “types” of processing and resource needs: some applications require more I/O, some less. Others are CPU hogs while others chew up memory at an alarming rate....
Mobile and tablet platforms are hyping HTML5, but many applications are bound to a traditional client-server model, making API performance a top concern for organizations. I recently received an e-mail from Strangeloop Networks with a subject of: “The quest for the holy grail of Web speed: 2-second page load times". Being focused on optimizing the user-interface, they appropriately quoted usability expert Jakob Nielsen, but also included some interesting statistics: 57% of site visitors will bounce after waiting 3 seconds or less for a page to load. Aberdeen Group surveyed...
While everyone was focused on cloud, JSON has slowly but surely been taking over the application development world
It looks like the debate between XML and JSON may be coming to a close with JSON poised to take the title of preferred format for web applications.
If you don’t consider these statistics to be impressive, consider that ProgrammableWeb indicated that its “own statistics on ProgrammableWeb show a significant increase in the number of JSON APIs over 2009/2010. During 2009 there were only 191 JSON APIs registered. So far in 2010 [August] there are already 223!”
Today there are 1262 JSON APIs registered,...
Database as a service is part of an emerging model that should be evaluated as an architecture, not based on where it might be deployed These days everything is being delivered “as a Service”. Compute, storage, platforms, IT, databases. The concept, of course, is sound and it is generally speaking a good one. If you’re going to offer an environment in which applications can be deployed, you’d best offer the services appropriate to the deployment and delivery of that application. And that includes data services; some kind of database. ...
Why these two are very different but complementary technologies Have you ever wondered why one network product is called a “controller” while another seemingly similar in function solution is called a “gateway”? There’s actually a very good reason for the naming and despite appearing to act similarly they do fill different roles in an architecture and are often called upon to work together. GATEWAYS If you loosely defined a gateway as a “converter” or “translator” you’d be very close to nailing down a simple definition. Gateways act as mediators between...
Infrastructure 2.0 ≠ cloud computing ≠ IT as a Service. There is a difference between Infrastructure 2.0 and cloud. There is also a difference between cloud and IT as a Service. But they do go together, like a parfait. And everybody likes a parfait… The introduction of the newest member of the cloud computing buzzword family is “IT as a Service.” It is understandably causing some confusion because, after all, isn’t that just another way to describe “private cloud”? No, actually it isn’t. There’s a lot more to it than that, and it’s very applicable...
Too often software design patterns are overlooked by network and application delivery network architects but these patterns are often equally applicable to addressing a broad range of architectural challenges in the application delivery tier of the data center.
The “High Scalability” blog is fast becoming one of my favorite reads. Last week did not disappoint with a post highlighting a set of scalability design patterns that was, apparently, inspired by yet another High Scalability post on “6 Ways to Kill Your Servers: Learning to Scale the Hard Way.”
...
The underlying premise of delivering information technology “as a service” is that the services exist to be delivered in the first place.
Oh, it’s on now. IT has been served with a declaration of intent and that is to eliminate IT and its associated bottlenecks that are apparently at the heart of a long application deployment lifecycle. Ignoring reality, the concept of IT as a Service in many ways is well-suited to solving both issues (real and perceived) on the business and the IT sides of the house. By making the acquisition and deployment of server...
